For the son to qualify for the $250k exclusion, I believe he would most likely need to meet the ownership and use test, meaning he needs to own and live in the home as his primary residence for at least two of the last five years before the sale.

That would be your house on the property line.

I’m glad you were able to move on without signing, shows the agent understands/is a good guy/gal, or knows other firms wouldn’t require such a signature. 

Hi, has anyone applied for a business line of credit with American Express? 

I almost exclusively sell bank foreclosures for a large asset management company, and I also do a lot of marketing for wholesale deals.

Buying a new primary residence has nothing to do with the capital gains exclusion.It is when you go to sell the new house down the line you'll run into a problem.

You should have an opt-out of the contract too, so if there is anything that you are not being represented correctly on you can opt-out of it as well. 

As a company we invest a lot into having top line service.

Converting properties to multi-family is considered extensive rehab and those programs are a little more exclusive than the standard bridge loan programs. 

So ultimately this may require a discussion with counsel, and you may have to settle on splitting the cost.
